Trial Design

2Treatment groups
Experimental Treatment
Active Control
Group I: Advance/Extend ManipulationExperimental Treatment4 Interventions
For ~2 weeks, Advance/Extend participants will advance bedtime and regularize wake time. The first night of the manipulation will be conducted in the lab under tightly-controlled experimental conditions. Participants will then go home and for the next 12 days will be instructed to: Sleep scheduling-- advance bedtime by 1.5 hours ( + sleep duration) Decrease evening blue light exposure via blue blocker goggles (2 hrs before bed) Increase morning bright light exposure via bright light goggles (30 min after rise) Monitor sleep, mood, and substance use via smartphone-based platform and wrist actigraph
Group II: ControlActive Control1 Intervention
Control participants will complete the baseline laboratory study, then maintain their habitual sleep schedules over the next 13 days at home, with no instruction on sleep timing or light exposure. Control participants will complete smartphone-and text-based assessments, thereby controlling for effort.
